Hello Codeforces Community!

Have you ever tried to find a common unsolved problem for you and your friends to practice on? Or maybe you wanted to quickly compare your combined problem-solving stats without juggling multiple browser tabs?

It can be a hassle, right? Therefore, hereby I present to you CF aggregrator !!

CF Aggregator is a simple, fast, and clean web tool that lets you combine data from multiple Codeforces handles into a single, unified dashboard.

What Can It Do?

Multi-Handle Aggregation: Just enter a few handles separated by commas, and the tool will fetch and combine all the data for you. It's perfect for teams or practice groups.

Combined Dashboard: Get a quick overview of your group's collective stats. See the total unique problems solved, the highest max rating in the group, total submissions, and more.

Visual Statistics Tab: A very smart idea to track progress inspired by cf analytics

Smart Problem Finder: This is the core feature! You can filter the entire problemset by: ->Rating: Find problems of a specific difficulty (e.g., 1600). ->Tags: Look for problems on specific topics (e.g., dp, graphs).

Solved Status: Instantly hide all problems that any of the users have already solved. This is a game-changer for finding fresh practice problems for your group.

Contest Finder: Find past contests based on your group's participation. For example, you can easily find a Div. 2 contest that none of you have any submissions in, making it perfect for a virtual contest or upsolving session.

Lastly, guys it was just an idea that was brought to life all by google Gemini. Also special thanks to qtpi for assistance

Thank you very much,

Happy Coding :)
